1 with, that you just mentioned, is the fact that on Georges Bank, there 



2 is a much greater concentration factor and we didn't see it. 



3 I guess if Jim says that in all the studies so far, he doesn't see 



4 a problem with metals, I just would say that Georges Bank would confirm 



5 that. I don't automatically think that in a canyon area, you would 



6 enhance the problem from the solids that are introduced from the 



7 drilling. 



8 DR. RAY: With all the other fines coming into the depositional 



9 area like that, your signal would be even more obscured, trying to pick 



10 up metals from the fines associated with just the drilling discharge, 



11 moving with all the other materials coming into that depositional area. 



12 DR. BUTMAN: I would say the reason why you don't see it in 



13 Georges Bank and some of the other areas is because the fines have been 



14 transported away. They are not settling out and they are being 



15 transported away. 



16 Here, this may be a case where the trace metals--all the trace 



17 metals--the worst case scenario would be that all the trace metals that 



18 are deposited would accumulate there. I think the reason why you don't 



19 see it on Georges Bank or somewhere else is that they are diluted 



20 tremendously as they are carried away. 



21 In this case, the potential for dilution may not be as large. 



22 DR. TEAL: All the evidence we have for concentration comes from 



23 his work and it shows that a two-fold concentration may be up to two- 



24 fold of Plutonium? 



25 DR. BOTHNER: Two-and-a-half. 



26 DR. TEAL: So, that's the kind of factor that we might expect, 



27 based on whatever evidence we have. 



28 DR. GRASSLE: That's an exploration rather than a drilling. 



29 DR. TEAL: No, this is from plutonium and lead. 



30 DR. GRASSLE: I'm talking about what Mike said. 



31 DR. BOTHNER: John is referring to the lead-210 and the plutonium 



32 in the canyons. 



33 DR. GRASSLE: Oh, I see.
